Hello Chris
Thanks for your question!

1. Community - really many great people around it, and in Cardano eocsystem, something which some other crypto communities lack
2. A way to grow Cardano ecosystem and allocate funds for it. Basically, those who are very interested can work in Catalyst and on own projects full time. Yes, many projects fail, some might seem irrelevant or inefficient, but in general there is a room for many interesting things in different geographies and areas.
3. Technology and its evolving. Being not perfect, Catalyst is improving and has possibilities to improve
